从火星Chryse Planitia地区收集的两个表面样品被加热到高达500 ℃的温度。用气相色谱-质谱联用仪分析了它们释放的挥发物。仅检测到H2O和CO2。这意味着有机化合物并未累积到可以在样品中检测到109重量份中几份的个别成分的程度。根据这一限制，讨论了有机化合物的积累和破坏的拟议机制。
Two surface samples collected from the Chryse Planitia region of Mars were heated to temperatures up to 500.degree. C, and the volatiles that they evolved were analyzed with a gas chromatograph-mass spectrometer. Only H20 and CO2 were detected. This implies that organic compounds have not accumulated to the extent that individual components could be detected at levels of a few parts in 109 by weight in the samples. Proposed mechanisms for the accumulation and destruction of organic compounds are discussed in the light of this limit.
